IBM TSS2 test suite

version 0.4.0:
- swtpm:
- Invoke print capabilities after choosing TPM version
- Add some recent syscalls to seccomp blacklist
- swtpm_cert:
- Support --ecc-curveid option to pass curve id
- swtpm_setup & related scripts:
- Rewrite swtpm_setup.sh in python with TPM 1.2 not requiring tcsd
and TPM tools anymore; new dependencies:
- python3: pip, cryptography, setuptools
dropped dependencies for swtpm_setup:
- tcsd, expect, tpm-tools (some still needed for pkcs11 tests)
- Added support for RSA 3072 keys (for libtpms-0.8.0) and moved to
ECC NIST P384 curve; default RSA key size is still 2048
- Added support for --rsa-keysize option
- Extend script to create a CA using a TPM 2 for signing
- tests:
- Use the IBM TSS2 v1.5.0's test suite
- Add test case for loading of an NVRAM completely full with keys
- Have softhsm_setup use temporary directory for softhsm config & state
- various other improvements
- man pages:
- Improvements
- build-sys:
- clang: properly test for linker flag 'now' and 'relro'
- Gentoo: explicitly link libswtpm_libtpms with -lcrypto
- Ownership of /var/lib/swtpm-localca is now tss:root and
mode flags 0750.
version 0.3.0:
- swtpm:
- Support for applying 'TPM Startup' command during initialization
- Use writev_full rather than writev; fixes --vtpm-proxy EIO error
